Introduction to VPNs, PKI, and PGP

Hello, in this module we continue our discussion of encryption and we look at some practical
applications of it. We start off by looking at VPN’s or virtual private networks and see how you can
use them to create secure communications using public networks such as the Internet. We than
briefly look at the problem of key management and finish our discussion with a look at PGP or Pretty
Good Privacy, which is an application that allows you to encrypt files and send encrypted email.
